The crew of the Starship Enterprise returns home after an act of terrorism within its own organization destroys most of Starfleet and what it represents, leaving Earth in a state of crisis. With a personal score to settle, Capt. James T. Kirk (Chris Pine) leads his people (Zachary Quinto, Karl Urban, Zoë Saldana) on a mission to capture a one-man weapon of mass destruction, thereby propelling all of them into an epic game of life and death.
